--- Begin Message ---Hello everyone, I am searching for an alternate way to accomplish user synchronization. I would like two or more users to block on the read of some stream, so that when one person writes to it, the other person(s) will read it. The only way I currently know to do this is with the socket functions. However, this poses a small problem. If I use the socket functions, I have to keep a script running on the server at all times. I would really like to have users block at the end of a file until new information is appended. I certainly don't want to have all my clients sit in infinite while loops, and I'm sure my isp doesn't either. I may be shit out of luck anyway, if they are killing processes that run for too long. I appreciate any and all suggestions. If someone knows exactly which functions block, aside from the socket functions, could you please tell me? Thank you. Respectfully, Chad--- End Message ---

I Well, we don't distribute *nix binaries, so nothing comes 'built in' per se--you have to select which extensions to build at configure time.

I don't have the answer you're looking for (maybe it's a php.ini setting), but I suspect that it might be a dangerous idea. The longer a session ID is hanging about, the easier it is for a cracker to hijack it and use it for evil intent. Remember, every time a page is requested within any given session, either a cookie variable or a GET variable is being sent along with the HTTP headers. Keeping a session going for more time than needed means that the variable representing the session ID is leaving footprints all over the place.

If each user has a unique user id, then make a table called seen_briefing: create table seen_briefing ( id int(11) unsigned not null default '0', primary key (id) ) Make an entry once a user has seen whatever they need to. Then, on their next login, do a join against the seen_briefing table, check for an entry... -- Greg Donald--- End Message ---
--- Begin Message ---Hi Justin, are you using <?php session_start(); ?> at the top of every page you want to keep the session? Cheers, Joe :) Justin Deutsch <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi All, > > I am running Apache with PHP4 as a module. I have also written a script (template.php) that sets up the default envrionment, like the CSS and navigation etc. The script also reads in a file, as defined by the ?path= of the URL. The file it reads in must have the sections (includes, header and body, as defined by /*** ***/ and /*** end ***/ pairs). The file is the split into these sections and along with the templated bits of the page compile into a single string which is the executed using the eval(). Now this all works fine, but I also want to use sessions. The first session from the index.html file, which is first acessed as a login page, stores the player class fine, but when I go to the next page (player_login.html) I seem to loose the session. > > You might ask why I don't just use an existing templating system, well it's because I think that you should only have to write the template once and not have to touch it again. The templating systems I have come across force you to include a file at the top and bottom of the code you are writing. The one down side to the way I am doing it is that I have had to force the other file into a include, header and body section, but this is a trivial formatting issue. > > Is there something I'm missing?

If divisible by 50, another que is filled, etc. The footer has a script that checks a table with each que status and then does does a few things out of the highest priority que. I figure the user will not notice a few small scripts running after all the text is displayed. If there is a better way, let me know!! Thanks, Jeff--- End Message ---

One way to do it (stole this from my 'Beginning PHP' book [Wrox]):
Store the current timestamp into a file. Read this file every time some
commonly-used feature of your site is executed. Then, when X number of
seconds has passed beyond the timestamp, execute some other code:
$countfile = "./countfile.txt";
$fp = fopen($countfile, 'r+');
$oldtime = fread($fp);
if ((time()) >= ($oldtime + 24 * 60 * 60 * 7)) {
// a week has passed since the last time the file was written to
// execute the code (mail or whatever)
}
rewind($fp);
fwrite($fp, time());
fclose($fp);
or something like that. NB this code is definitely untested, so it
probably won't work, but the theory is there. Also, be sure to take
into account the security issues of having a file writeable by your web
server -- I'm assuming you already have experience with this.

Hello!
>From my understanding of your question, I'd say that you'll
have to configure Apache so that it calls PHP for XML-files,
too. You can set this up in your either ".htaccess" files or
in your Apache config file (-> see the docs, I don't know
exactly 'cos I'm using IIS/5.0 with Win2k). This is what I
use for on my ISPs virtual web server:
AddType x-mapp-php4 .xml
AddType x-mapp-php4 .xhtml
DirectoryIndex index.xml index.xhtml
IndexIgnore .htaccess .htpasswd
The <?php [...] ?> - tags should then be processed _before_
the browser.
An alternative to using XML is using XHTML 1.0 (either
transitional or strict) in your .html - files:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
<head></head>
<body></body>
</html>
Don't forget to end your empty tags with /> instead of >, like this: <br />
Hope it helps, regards,

Do I need to now place some kind of header in all my xml files or is there some type of apache config that needs changing? Now all xml displays as text even if I don't use php commands. I assume because of the ext is getting process before the mime type text/xml line or something?

Hi guys,
I am not sure if this is possible. Not on my knowledge, but maybe someone is
smarter than I am :-)
I want to pass an icon to a function. Therefore I am putting all the html
into a var called icon.
Inside this html their is another variable with an array which value is set
inside the function.
How can I pass this html thing and ensure that the variable is gonna be set?
Take a look at the code underneath.
Like that it is just printing out $picture_id[$i]
$icon_1 = " <a href=\"index.php?fuseaction=edit&action=delete&id=%s\"
onclick=\"return confirm('Are you sure you want to delete picture no:
$picture_id[$i]');\">
<img src=\"../app_global/pics/delete.gif\" width=20 height=20 border=0
alt=\"delete\">
</a>";
Can anybody help on this?
Thanx for any help
Cheers Andy

Well, as long as you use double quotes: " the variables will be parsed
inside you statement... single quotes however mean the exact string...
example:
$icon = "1.jpg";
$str = "this is the image $icon";
$str2 = 'this is the image $icon';
print $str; // returns: "this is the image 1.jpg"
print $str2; // returns: "this is the image $icon"
Greets,

Hello =)
I have a template stored in a database which contains variables. Then, in a
separate file, I have the variables set, and I call the template and run it through
eval(). Unfortunately, it only is parsing a few of them. Could somebody take a look
and give me some input?
Thanks

Here's what my template table looks like:
CREATE TABLE templates (
id tinyint(4) unsigned NOT NULL auto_increment,
name varchar(16) NOT NULL default '',
template text NOT NULL,
PRIMARY KEY (id),
UNIQUE KEY name (name)
)
Then here is my template function that preps the data for use with eval():
function template($name, $set="main"){
global $tb_templates;
$sql = "
select
*
from
$tb_templates
where
name = '$name'
";
if($query = sql_query($sql)){
if(sql_num_rows($query)==1){
$array = sql_fetch_array($query);
$template = str_replace("\\'","'",addslashes($array["template"]));
} else {
$template = $name . " template not found.";
}
}
return $template;
}
Then here is how to use eval() properly:
$template_name = template("template_name");
eval("\$template_name = \"$template_name\";");
This will parse all your $vars you store in the templates.

--- Begin Message ---Hi list I have some buttons made in photoshop in .gif format.

button.php
<?php
Header("Content-type: image/gif");
$string=str_replace("%20", " ", $string);
$theimage = "images/" . $button .".gif";
$im = imageCreateFromgif($theimage);
$white = ImageColorAllocate($im, 255, 255, 255);
$font = "/fonts/VERDANAB.TTF";
$box = imagettfbbox ( 12, 0, $font, $string);
$th=$box[7]-$box[3];
$th= $th + 2;
$py = (imagesy($im) -$th)/2;

$size = 12;
ImageTTFText ($im, $size, 0, $px, $py, $white,$font,$string);
Imagegif($im);
ImageDestroy($im);
?>
fot this to work you need to upload VERDANAB.TTF to a folder called 'fonts'
and you call the image like this:
to draw 'hello' on a button called 'mybutton.gif' stored in 'images' folder
<img src="button.php?string=hello&button=mybutton">

Rodrigo,
I've been struggling with this for some time, so here goes:
The php4 builds do not support .gif files, you'll need to change your files
to .jpg or .png format, or use php3 (I can't change to php3).
I use imagecreate() func. before imagecreatefromjpeg() func. because if I
didn't do this, the added text would be gray regardless of the desired
color.
The mysql portion is solid and yields the desired results.
However, I'm having trouble with something related to the
imagecreatefromjpeg() func., I get a server error (500) on some images
regardless of their size. This is the only error produced by the func. and
it is maddening. From experimentation, I believe that there's something
wrong with the .jpg files, the .jpg file upload, or the phase of the moon.
Good luck,
Hugh

This is not true. GIF support depends solely on the version of the GD library PHP is linked against. GIF support was not removed from PHP. It was removed from later versions of the GD library. Simply grab an older version of GD which has GIF support and link PHP against that. -Rasmus--- End Message ---

I am looking for a good manual or introduction on how to write readable,
extensible code (in any programming language). To give you an example,
this bit looks pretty darn horrible and I just don't know how to
rephrase it to make it more concise and readable:
----------------------------- snip -----------------------------
if ( ($var>0) & ( (strlen($var)==strlen(intval($var))) or
((strlen($var)-1)==strlen(intval($var))) ) ) {
do stuff;
}
----------------------------- snap -----------------------------
(actually, depending on how you've configured your mail reader, or how
your terminal is set, this boolean expression may acually not appear in
one line . . . which is a problem in itself)
I am not sure why, but one problem that I happen to run up against is
that I write expressions (boolean) which get very long and because you
can't split them (what with them being conditionals in if clauses) - or
can you? - they stretch off the screen which makes my code pretty much
unreadable (I noticed that good-looking code tends to stick with, like,
70 or something characters in width).
But that's just one problem.
The stuff that I do always works, but I always have difficulties
understanding it once I come back to it after a while (the fact that I
am also lazy at commenting is not the issue - it is my belief that
well-written code should be readable as well as functional).
There must be some kind of canonical text on the subject matter, just as
there are canonical texts on SQL (Codd, Celko), C (Kernigan, Ritchie),
Perl (Wall), epistemology (Kant), the laws of motion (Newton), general
relativity (Einstein), psychoanlysis (Freud) . . . you name it.

This is all just IMHO, because I'm still a bit of a beginner.
I have always been tempted to write code in the fewest lines possible. But
sometimes this is a Bad Thing, because it can make it very difficult to
figure out what you were thinking when you wrote it. I think readability
is more important, especially in PHP apps where you are not trying to
squeeze out every last bit of performance (don't get me wrong, speed is
important, but let's face it, we're not designing low level device drivers
or real time kernels here...)
Anyway, not really knowing what you are trying to accomplish above, I would
rewrite it like so:
$strlength = strlen($var);
$intlength = strlen(intval($var));
if($strlength == $intlength || $strlength - 1 == $intlength) {
$length_ok = true;
}
if($var > 0 && $length_ok) {
do stuff;
}
Yes, that is 6 more lines of code than your example, but I believe it is
much clearer and easier to read. Also, the above is actually self
documenting IMHO. If I was going to use your example in my code, I would
definitely have to comment it to remind myself of it's purpose later, where
my example I believe doesn't require comments as it's easier to read.
Don't have any specific book recommendations...maybe someone else will jump
in and suggest something...

I am trying to develop a music scheduling system on Windows using the
command line to fire off WinAMP. The first exec works fine, then it
stops
and says that program execution time has been exceeded.
An example would be:
exec ("winamp.exe M000001.mp3");
a while loop kicks off the second. I tried to send the output to null
winamp.exe >null or nul and no luck. Anyone else try this on Windows?
Thanks,

I’m trying to control the way a new window opens when submiting a form.
When I do it from a regular button, I use:
<p align="center"> <a href=""#pv"" >rollbars=0,width=300,height=340,top=150,left=150');return true">
and it works, it opens the new window, but I’m not transferring any values in here.
What I want to do is that when I push the submit button of a form, it opens in the same window size as the prior example. I hope you can assist me.
